You guys are nitpicking arguments. Point is that Wavedashing, along with other techniques, contributes to the high APM of Melee. A high APM can not only turn off players thinking of playing seriously but can cause hand issues in the long run for some.
Secondly, the APM of Melee is inflated by the gravity/physics of the game. Everyone in melee falls faster and moves quicker than Brawl, 4, and Ultimate. Even if you ported all the mechanics of Melee 100% perfectly to Ultimate, Ultimate will still have a lower APM simply because the physics are slower.
Third, I'm not sure where you get that wavedashing is unintuitive. That's a subjective take if nothing else. It's pretty inuitive to me, and other people. :wacko:
